Not too long ago I got rid of a virus (With the help of somebody here) and since I got rid of it (but not while I had it) My CPU and Memory usage have been higher. normally With 3 or 4 tabs of google crome,Skype and Avast Open My CPU usage moves between 4, 5,7 and maybe 14 Now it's going between 12,16,18,22, and goes to up around 100 when opening most anything. where as My memory is usually 1.53 GB (With Previously stated stuff open) And with skype alone open it's at 1.88 with one tab of google crome it goes too 2.14 GB. It probably sounds like a viruses doing but 3 different scans, (Eset, Avast! and Malware-Bytes All Full scans) haven't found any more viruses afterwards.
Edit: I didn't think of running Rkill I did and it got these:
Processes terminated by Rkill or while it was running:
C:\ProgramData\Skype\Toolbars\Skype C2C Service\c2c_service.exe
